Going to go with as few pens inked as I can for the month. I'm tired of having nine pens inked with eight of them sitting.
Rolling with a Sheaffer 330 (M) as my EDC for a while; I think it has Pilot Blue/Black. A Pilot Metropolitan (EF) with Waterman red will be for work, and I have an Airmail ebonite pen with a fine stub filled with Diamine Med Blue at the home just to try out.
I'll probably clean and store the other pens for now.
TWSBI 580al Orange with iroshizoku shin Kai, KarasKustoms Ink with Sailor Epinard, and a Kaweco AL Sport with Diamine graphite. Don't normally have this many pens on me...
